ACETYLENE-GAS GENERATOR.

" SPECIFICATION forming part of Letters :Patent No. 624,203, dated May 2, 1899.

Application nea september 17,1898. serial No. 691,259. (No model.)

,l'b @ZZ whom it may concern:

Be it known that I, JOHN D. FORSYTH, of Claremont, in the county of Ontario and Province of Ontario, Canada, have inventedcertain new and useful Improvementsin Acetylene-Gas Apparatus; and I hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to certain new and useful improvements in acetylene-gas apparatus, and relates more particularly to the arrangement and construction of the carbidholder and the manner in which it is lowered into and raised out of the Water by the fall and rise, respectively, of the floating part of the gasometer, and it also relates to the manner in which the gas is purified as it passes from the gasometer to the mains; and the object of the invention is to so arrange the carbid-holder that when the floating part of thev gasometer is in its lowered position it will admit of the contact of a small quantity of water to the carbid and atomize the water as it passes to the carbid, and when the iioating part of the gasometer is in its raised position it will hold the carbid entirely free from contact with the water in the gasometer.

It is also part of the object of the invention to so arrange the carbid-holder that it can be Weighted to facilitate the lowering of the iioating part of the gasometer and create a pressure on the gas; and the invention consists, essentially, of a gasometer embracing in its construction a gas-well having an open top, and a gas outlet pipe extending approximately from the top of the gas-Well through the bottom to a purifier connected to the outer side of the bottom of the Well, and a safety escape-pipe extending approximately from the top of the Well through the bottom and to which is adapted to be connected a pipe leading to the outlet from the building, and a floating part for the gasometer having a pipe adapted to iit the safety escape-pipe of the gas-well and fitted in close proximity to its lower end with an opening which, rising above the topof the safety escape-pipe of the gas-Well, forms an outlet from the gasometer `tional view on the lines b b, Fig. 1.

the top of the iioating part of the gaso'meter and connected with the safety escape-pipe, which when the valve is open allows the gaseous contents of the gasometer to pass out through the safety escape-pipe during the descent of the iioating part or to enter the gasometer through the safety escape-pipe and tube while the iioating'part is being raised to be removed, and a generator consisting of a 6o tubular socket screw-threaded at' its upper end and containing aremovable perforated carbid-holder extending from approximately the top of the socket midway to the bottom, and a top having a screw-threaded collar fitting the screw-threaded top of the socket, a perforated disk above the collar, a central pipe extending slightly below and above the perforated disk, establishing an outlet for the gas from the carbid-holder, openings through 7o the top of the collar, and a weighted pocket within the top above the openings, as hereinafter more fully set forth, and more particularly pointed out in the claims.

In the drawings, Figure l represents a perspeotve View of the complete apparatus. Fig. 2 is a sectional View of the same on theV lines a a, Fig. l. Fig. 3 is an enlarged sectional view of the generator. Fig. 4 is a sec- Fig. 5 is 8o a perspective view, partly in section, of the purifier. Fig. 6 is a sectional View of a modication of the carbid-holder and top of the iioating part of the gasometer.

Like letters of reference refer to like parts throughout the specification and drawings.

A represents the gas-Well, which is of any suitable size and shape, consisting, as shown in the drawings, of a cylindrical wall a and a bottom ct', tightly connected to the lower 9o end of the wall a.

B represents the purifier, located at the bottom of the outer side of the gas-well A.

O represents an outlet-pipe extending approximately from the top of the gas-well A throughthe bottom a to the purifier B. It is advisable to have the top of the pipe C slightly below the top of the gas-well A, although it is not necessary to do so.

through the safety escape-pipe, and an air inlet and outlet forthe gasometer consisting of a valve-controlled tube extending through D represents a drain-pipe fitted to the ,gasroo well A in close proximity to the bottom a@ and provided with a valve E, the purpose of f the drain-pipe D being to draw off the water within the gasometer when it is required to do so.

F represents a safety escape-pipe extending from approximately the top of the gas-well A through the bottom a' and tted to receive a pipe connection to the outlet from the building. The top of the safety escape-pipe F is on the same level as the top of the outletpipe C.

G represents the floating part of the gasometer, which moves vertically within the gas-well A. The floating part G consists of a cylindrical wall g and a top g', tightly connected to the wall'g.

H represents a safety escape-pipe extending through the top g to near the bottom of the wall g. The bottom of the pipe H is open, and formed through the side of the pipe H, above the bottom h, is an opening h. When the parts are assembled in position, the pipe F telescopes'with the pipe H, and when the floating part G has been raised to its most elevated position the opening h is above the top of the pipe F, While the lower end of the pipe F is still within thepipe H. When the opening h is above the top of the pipe F, the gas passes from the gasometer through the opening h' and pipe F to the outlet from the building. By this means the danger of accident through overcharging the gasometer is avoided.

I represents a pipe fitted through the top g.' and provided with a valve 'i to open or close the passage through the pipe.

J represents a coupling forming a connection between the pipes H and I.

When the parts are being assembled before the manufacture of gas is commenced, the` valve i is open to allow of the air passing from the gasometer through the pipe I, coupling J, tothe escape-pipes H and F, to the outlet to the building, and when the air within the gasometer is. exhausted the valve t' is closed V.to close the outlet to prevent the escape of gas While being manufactured.

The purifier, as shownV in the drawings, is substantially drum-shaped; but I do not confine myself to any particular shape or size for the purifier, as I may build it of any other shape suitable for the purpose. The outlet-4 pipeA C enters the purifier above the waterlevel and extends nearly to the bottom so that the gas when passing through the purifier must necessarily pass through the purifying liquid contained within it.

K- represents the outlet-pipe from the purifier B. The pipe K is fitted to the purifier above thelevel of the purifying liquid and is adaptedr to be connected to the gas-mains of the building.

L represents an inlet for the purifying liquid fitted with a valve M, and N represents the drain-pipe fitted to the bottom of the puritler for the purpose of draining off its liquid contents when found necessary to do so.

' O represents the generator, which consists of a cylindrical socket 0, screw-threaded at its upper end o'. The socket o is provided with an annular flange or shoulder o" below the screw-threaded part of the end 0.

P represents the carbid-holder, which correspondsin shape with and is'slightly less in measurement than the interior of the socket o. The holder P consists of a cylindrical wall p and bottom p. The upper end of the wall p is provided with a circular flange p, which is adapted to rest upon the shoulder o and sustain the holder in position. The holder P is of a less depth than the depth of the socket o in order that a pit may be formed in the socket to receive the ashes or residue from the holder. The wall and bottom of the holder P are perforated to allow of the ashes passing to the pit or bottom of the socket. Although I have shown in the drawings the holder to consist of a perforated metal, I may, if I find it so desirable, make the holder of wirenet ting or of any other material suitable for the purpose.

`Q represents thetop of the generator, which consists of an elongated collar Q', having an internal screw-thread at its lower end corresponding in all respects to the screw-threaded end o of the socket O. Formed through the sides of the collar Q,above the screw-threaded part, are a series of openings Q,and connected to the interior of the collar Q', between the top of the screw-threaded part and the openings Q, is a perforated disk R. t

S represents a pipe passing centrally through the disk R and extending slightly above and below the same, the pipe S forming the means of escape for the gas from the carbid-holder through the openings Q to the gasometer.

`T represents a pocket formed in the collar Q above the openings Q to receive lead or other weighty substances.

The top of the collar Q is provided with a flange U, by means of which it is permanently attached to the under side of the top g.

When it is required to charge the generator, the socket is unscrewed vfrom the collar Qand the carbid is placedin the holder P. The socket is then screwed to thecollar and the floating part G is placed in the gas-well A. The air in the gas-well A would naturally sustain the floating part in an elevated position, and to overcome this difficulty the valve t' is opened to allow of the air passing through the pipe I and coupling J to the escape-pipes F and H and outlet to the building. The air will naturally pass to the outlet by means of these pipes, and during its passage the floating part will gradually fall. When the air has been exhausted in this manner from the gasometer, the valve t' is closed and the ap-A paratus is ready to commence the manufacture of gas. Before the floating part G is vplaced in position in the gas-well A the gaswell is partly filled with water to form a seal for the bottom of the floating part. When the floating part has descended to its lowermost position, the generator is brought into IOC IIO

contact with the water, and the water, passing through the openings Q, enters the collar Q and passes through the perforated disk R to the carbid in the holder P, the perforated disk atomizing the water as it descends into the holder and practically spraying it upon the carbid. The gas generated by the union of the water and carbid passes through the pipe S and openings Q" tothe gasometer and causes the fioatin g part Gr to rise and continue to rise until the gasometer is fully charged. In the event of the manufacture of gas conits limit of safety the opening h in the escapepipe I-I will rise above the top of the escapepipe F and allow the overgeneration of gas to pass from the gasometer, through the escape-pipe F, to the outlet from thebuilding,

Aand when the overgenerated gas has escaped the fioating part of the gasometer will descendto bring the opening 7L below the top of the safety escape-pipe F and close the passage from the gasometer through the escapepipe. The gas passes from the gasometcr to the mains through the outlet-pipe C and through the purifier B and outlet-pipe K. During the exhaustion of the gas from the gasometer the fioating part G will descend and bring the generator again into contact with the water in the well A, allowing the water to pass through the openings Q and perforated disk R to the holder P and generate a fresh supply of gas, this being continued until the carbid or water or both havebeen completely used up.

When charging the carbid-holder, (shown in Figs. 2 and 3,) it is necessary to remove the floating part of the gasometer. To 0bviate the necessity of this removal,-the top of the fioating part G is provided with a central opening surrounded by an elongated collar G5, which collar is surrounded by a sleeve GG, arranged to form, with the top of the floating part, a compartment to contain water to form a water seal. The collar Q is eX- tended above the top of the Water seal and is closed by a cover Q5, having a downwardlyextending flange Q6 to enter between the sleeve G and collar G5. By means of this construction the carbid-holder can be removed without removing the floating part of the gasometer.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a gasometer, a generator embracing in its construction a collar fitted to the under side of the top of the floating part of the gasometer, a socket detachably connected to the collar, a carbid-holder sustained within a carbid-holder sustained within the socket,
